Synthesis and characterization of novel PCA-PEG-PCA triblock copolymer

摘要

Using chloroacetic acid(CA) and polyethylene glycol(PEG) as raw material, polyacetic acid-polyethylene glycol-polyacetic acid(PCA-PEG-PCA) triblock copolymer was synthesized by solution polycondensation. The triblock copolymer was characterized by FT-IR spectroscopy, X-Ray Diffraction and DSC. The structure of copolymer was confirmed by FT-IR. The crystallinity of compolymer was 51.24% investigated by XRD, and the result of DSC showed the PCA and PEG was homogeneous with a good compatibility.
